This invention relates to metal-binding machines and more particularly to a machine for attaching metallic binding elements to the corners or edge-s of pocketbooks or the '5 like.

An object of this invention is an improved, eihcient and inexpensive machine of this character which securely fastens the binding element quickly and expeditiously.

Other objects, novel features and advantages of this invention will be apparent from the following specification and accompanying drawings, wherein Fig. 1 is a plan view of the machine;

Fig. 2 is a front elevation thereof;

Fig. 3 is a section on the line 3-3 of Fig. 1, with the parts in inoperative position;

Fig. 4 is a view similar to Fig. 3, with the parts in operative position;

Fig. 5 is a section on the line 5-5 of Fig. 3; and

Figs. 6 and 7 are detail views.

rIhe machine comprises a bed 10 which may be fastened to a workbench or other support.

A block 11 is attached to the plate 10 bybolts 12. This block is substantially rectangular in cross-section and is provided at one end with a V-shaped recess 13. The block 11 is also provided with bores in which are slidably arranged the rods 111. rFliese rods carry at their upper end a plate 16. Interposed between the block lland the plate 16 are aplurality of springs 17 which tend to keep the plate 16` out of contact with the 3Q block 11.

A bolt 13 passing through the plate 16 and threaded into the bleek 11 limits the movement of the plate 16 under the influence of the springs 17. A yoke 19 has its legs passing through apertures in the frame 10, the ends of the legs being attached to the plate 16 by means of bolts 20. An operating rod 21 is screwed into lthe bow of the yoke and provides means whereby a pull may be erted on the yoke 19 to move the plate 16 towards the block 11. A

By means of the bolt 22, a pressure head 23 is attached to the plate 16. This pressure head is shaped to ht into the groove 13 in the endv of the block 11 and is designed to slide up 'and down in this groove. A pressure foot 2a' is carried by the head 23 and is also shaped to conform to the groove 13. The pressure foot is provided with an upstanding lug 25 fitting into a sliot in the head 23. A bolt 26 carried by the head 23 has its end extending into a groove provided in the lug 25 to attach the pressure foot to the head and at the same time permit slight pivotal movement of the former relative to the latter.

`A resilient member 2T is carried by the plate 16 and comprises a resilient piece of steel which is arranged obliquely to the direction of movement of the plate 16 and slants downwardly toward the block 11. 1t is adjustably attached to the plate 16 by bolts 28 passing through slots in the upper end of the member 27 and threaded into the plate 16. Vertical adjustmentA of the member 27 is accomplished by means of the adjusting screw 29. At the lower end of the member 27, there is provided a friction strip 30.

Gage elements 31 are provided for effecting the proper positioning of an article to be operated upon with respect to the other elements of the machine. That portion 32 of the plate 10 which is arranged directly below and in line with the pressure foot 24 is made removable so that it may be taken out and polished when such action is required.

In the operation of this device, a pocket-4 book corner 33 or the like with a clip or binding element 34 arranged over the corner is introduced into the machine with the binding element resting on the inner end of the removable portion 32 and in contact withthe walls of the groove 13. rlhe yoke 1S) is then pulled downwardly through the medium of any suitable power applied through the rod 21. This causes the head 23 and the plate 16 to descend, thus bringing the friction member 3() into contact with the pocketbook or other device to the corner of which a binding element is being applied. Due to the slant of the member 27, the friction strip 30 exerts pressure upon the pocketbook to move the same toward the block 11, thereby forcing the edge of the article 33 definitely into contact with the rear interior wall of the binding element as well as pushing the binding for moving toward said pressure foot the ar-`v lof less thickness than the other.

element into firm contact with the walls of the groove 13. The pressure foot 24 next` comes into contact with the binding element 34 and firmly clamps the same on to the pocketbook corner. The member 27 maintains the article 33 and the clip 34 in immovable relation to the bed 10 whilepressure being applied to the clip. Inkmany instances, the corner clips or binding elements are applied to articles one of the edges of which is In such case, the pressure head 24 pivots slightly about its support so-that sufficient pressure is applied both to the thick and the thin part to effect anchoring of the clip to the corner.V

A thin metal shield 35 is carried by the plate 16 along itsside and rear and depends over the' block 11. Y A plate 36 is attached to `Athe top of the plate 16 bybolts 37. 1 The shield 351Aand plate 36 cover and protect the working parts and improve the appearanceof the ma- V chine. i

It is apparent, of course, that various strucv tural modifications may be made in the device y above ldescribed without departing inany way from the spirit of the invention as dened in the appended claims.n l
